he's got tall slicks which result in better traction but lower trap speeds

What is stock pressure on the CDFP in the cobalt? How much of an increase is 2750psi?

06blackg85ss · 11-03-2009, 01:36 PM

1750-2000psi

1.9 60 foot, and slicks. they are 26 inch which has been stated but it does slow you down a little. I trap 114 but have hit a couple 115 traps on street tires. 111mph trap with a 1.7 60 is good for 11's, so the 60 is crucial

Deadman · 11-03-2009, 02:47 PM

was there a saftey release valve that prevented the cdfp from going over the limit? Need to know how this 2700+psi was achieved ! :P Good work none the less zzp

General rule of thumb- every tenth you drop in the sixty foot is worth two tenths in the 1/4 mile ET. If he ran a 1.8 sixty foot, then it matches perfect. .7 slower sixty foot = 1.4 slower ET.

With a 1.70 sixty foot and clean, quick no-lift-shifts, we should be looking at an 11.3, which would great at only 20psi. Maybe next time...

You should post some of those logs on the hptuners forum, Chris from hpt always likes to see logs when the ecm is doing something funky. Im sure you already disabled the overboost codes yet its still shutting you down.

Its not overboost doing it

SportredSS · 11-03-2009, 06:06 PM

Well, the ZR1's are running 11.3 to 11.6 between 126-129 mph stock... this SS\TC would need some seriously sticky tires... I can see this car running 127-132mph... It should... My old 06' GTO with 570 whp ran 10.7 @ 133 .... This Ss should have no trouble devouring a stock C6 Z06 even with 440+ whp..... Plus some grip....

The fastest time for a C6 Z0 stock is 11.6 @ 125...>>> The typical track averages are: 11.8 @ 121 mph... The slowest C6 Z0 I've seen was 12.2 @ 118 mph.. Heck, the ZR1's have a serious problem with grip and it's actually slower to 80 mph then a C6 Z0 by a few tenths...... Put drag radisals on and the party is over....

Hey Matt how are you getting the Stg 4 clutchmasters unit to work???.... I've spent over $7000, 5 dealers and a performance shop and none of them can even get my stg 3 to engage\disengage... Finally one guy got it to work but engagement\disengagement is at the floor thereby eliminating the ability to NLS.. PLus I'm at 25 psi and the increased boost ( from 21-22psi) has lowered my whp on the dyno to 285 from 295..... My car was quicker when it was near stock..... 13 flat @ near 110mph in the 1\4 Now I cant get down the 1\4 in under 13.8 @ 102 mph....(due in part to not being able to do NLS) This stupid Stg 3 from Clutchmasters sucks......

I also took my upgraded exhaust off and back to stock and my airbox back to stock, guess what?, now my car is making more whp then ever.....

Go figure.....

stock C6 Z06 has done (i want to say 10.9) low 11's stock..i mean like 11.1
no doubt in my mind the C6 ZR1 can do 10's in stock trim

look up that guy ranger's videos on youtube.

EDIT: he already did it. 10.73 in a ZR1 on stock tires

drew1991sf · 11-03-2009, 08:44 PM

fail sportred
these are both on stock tires. a ss/tc wont touch either of those.....

We aren't running Clutchmasters- We have our own clutch setups made. As zoom pointed out, our adjustable clutch rod can help if your pedal is too low.

Sounds like you need some tuning as well.
